Females can conceive after they are a year and a half old; oestrous lasts for 24 to 48 hours, and occurs every 12–29 days in non-pregnant females.Gestation lasts six to seven months. Births generally occur in the midday; the female will isolate herself from the herd when labour pain begins.A single calf is born, and is immediately concealed in cover for the first few weeks of its birth. The fawn then joins a nursery group within its mother's herd. Calves are suckled for four to six months; young males, forced out of the group, join bachelor herds, while females may stay back.
